Abstract

A plastic drying apparatus that uses microwave heating as means of heating a plastic (1) thereby allowing the surface as well as the inside of particles of the plastic to be heated simultaneously and therefore can attain to bring the plastic to a highly dried state within a short period of time. A certain amount of a plastic is fed into a plastic drying tank (2). While the plastic is stirred, the plastic is heated and dried uniformly by microwaves (21) generated by a microwave generating unit (11). The humidity is measured by a humidity measuring sensor (9) and the plastic is highly dried automatically. Dried air nozzles are provided to the wall surface of the plastic drying tank for discharging air (22) in a super-dried state in a widely flared manner so as to prevent the plastic powder, etc. from adhering. <IMAGE>
